+# Amazon - Bedrock
+
+[Amazon Bedrock](https://docs.aws.amazon.com/bedrock/latest/userguide/what-is-bedrock.html) is a service provided by Amazon Web Services (AWS) that allows you to access large language models with a serverless experience. Semantic Kernel provides a connector to access these models from AWS.
+
+## Prerequisites
+
+- An AWS account and [access to the foundation models](https://docs.aws.amazon.com/bedrock/latest/userguide/model-access-permissions.html)
+- [AWS CLI installed](https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html) and [configured](https://boto3.amazonaws.com/v1/documentation/api/latest/guide/quickstart.html#configuration)
+
+### Configuration
+
+Follow this [guide](https://boto3.amazonaws.com/v1/documentation/api/latest/guide/quickstart.html#configuration) to configure your environment to use the Bedrock API.
+
+Please configure the `aws_access_key_id`, `aws_secret_access_key`, and `region` otherwise you will need to create custom clients for the services. For example:
+
+```python
+runtime_client=boto.client(
+    "bedrock-runtime",
+    aws_access_key_id="your_access_key",
+    aws_secret_access_key="your_secret_key",
+    region_name="your_region",
+    [...other parameters you may need...]
+)
+client=boto.client(
+    "bedrock",
+    aws_access_key_id="your_access_key",
+    aws_secret_access_key="your_secret_key",
+    region_name="your_region",
+    [...other parameters you may need...]
+)
+
+bedrock_chat_completion_service = BedrockChatCompletion(runtime_client=runtime_client, client=client)
+```
+
+## Supports
+
+### Region
+
+To find model supports by AWS regions, refer to this [AWS documentation](https://docs.aws.amazon.com/bedrock/latest/userguide/models-regions.html).
+
+### Inference profiles
+
+You can create inference profiles in AWS Bedrock to monitor and optimize the performance of your foundation models. Refer to the [AWS documentation](https://docs.aws.amazon.com/bedrock/latest/userguide/inference-profiles.html) for more information.
+
+When you are using an Application Inference Profile, you must specify the `BEDROCK_MODEL_PROVIDER` environment variable to the model provider you are using. For example, if you are using Amazon Titan, you must set `BEDROCK_MODEL_PROVIDER=amazon`. This is because an Application Inference Profile doesn't contain the model provider information, and the Bedrock connector needs to know which model provider to use so that it can create the correct request body to the Bedrock API.
+
+> An Application Inference Profile ARN is usually formatted as followed: `arn:aws:bedrock:<region>:<account-id>:application-inference-profile/<profile-id>`.
+
+### Input & Output Modalities
+
+Foundational models in Bedrock support the multiple modalities, including text, image, and embedding. However, not all models support the same modalities. Refer to the [AWS documentation](https://docs.aws.amazon.com/bedrock/latest/userguide/models-supported.html) for more information.
+
+The Bedrock connector supports all modalities except for **image embeddings, and text to image**.
+
+### Text completion vs chat completion
+
+Some models in Bedrock supports only text completion, or only chat completion (aka Converse API), or both. Refer to the [AWS documentation](https://docs.aws.amazon.com/bedrock/latest/userguide/models-features.html) for more information.
+
+### Tool Use
+
+Not all models in Bedrock support tools. Refer to the [AWS documentation](https://docs.aws.amazon.com/bedrock/latest/userguide/models-features.html) for more information.
+
+### Streaming vs Non-Streaming
+
+Not all models in Bedrock support streaming. You can use the boto3 client to check if a model supports streaming. Refer to the [AWS documentation](https://docs.aws.amazon.com/bedrock/latest/userguide/conversation-inference-supported-models-features.html) and the [Boto3 documentation](https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/bedrock/client/get_foundation_model.html) for more information.
+
+## Model specific parameters
+
+Foundation models can have specific parameters that are unique to the model or the model provider. You can refer to this [AWS documentation](https://docs.aws.amazon.com/bedrock/latest/userguide/model-parameters.html) for more information.
+
+You can pass these parameters via the `extension_data` field in the `PromptExecutionSettings` object.
